To all whom it may concern: i

Be it known that I, GERHARD DIERS, a subject of the Emperor of Germany, and ay resident of the city of New York, in the county of New York and State of New York, have innew and improved top which is so constructedV that when it is spun it risesto the ceiling and spins on the same a greater or less length of time and then drops to the iioor and also continues tospin. n

The invention consists in a top, formed of v a windwheel provided with acentral tubular stem, which stem has a notch at its lower end for receiving a cord which is passed through grooves and apertures of a holder having a longitudinal bore for receiving said stem and which holder serves for holding the top while spinning the same. A rod which acts as `a cushion is mounted to slide friction tight in the bore of the tubular stem.

The invention also consists in the c onstruction and combinations of parts and details as will be fully described and set fort hereinafter.

In the accompanying drawings forming a part of this specification and in which like letters of reference indicate like parts, in all the views, Figure l is a vertical sectional View of my improved ceiling top, the holder being also shown in section. Fig. 2 is a plan view of the same. Fig. 3 is a plan view of the holder. Fig. 4 'is a side view of the sliding rod in the stem of the top. Fig. 5 is a side view of the lower partofthe stem showing a modified construction.

The top proper vis composed of the windwheel A and its central stem B. The wheel A is made of thin sheet metal, celluloid, hard rubber, pasteboard, wood or other suitable material and has a central hub yC and a rim- D connected with the hubbya series of spokes E which are curved and shaped. like the blades of a propeller or of a wind mill wheel.

5o The stem B which has alongitudinal bore'F,

extending downward from the top, -is secured at its upper end to thehub C, and has its lower end tapered andprovided with anotch G.l In place of providing the notch G in the lower tapered end of the stem a notch G may be formed inthe side of the stem a short distance above the lower tapered end as shown in Fig. 5. l

A rod H, provided with a tapered upper end H', is mounted friction tight in the bore F in such a manner that it can slide in said bore with more or' less resistance. So as to give the rod the necessary resistance it is preferably split lengthwise and provided at the upper end of the slit with a small spreadingpiece J, of rubber or other suitable material,

as shown in Fig. 4.

The holder K into which the top is placed for spinning it, is composed of a block of wood, hard rubber, or other material so shaped that it can conveniently be grasped in the hand. It has a central longitudinal bore L, a groove M in its upper end and extending across the upper end of the bore L and a longitudinal groove O` in each side. A hole P extends from the lower end of each side groove O to the bore L and is slightly inclined downward. An endless cord S is passed up through the bore L from the lower end of the same, through the holes P; through the side grooves O and through the groove Min the upper end and over the upper end of the central bore, as shown in Fig. 1.

To spin the top, the lower end of the stem B is placed on that part of the cord S directly above the upper end of the bore L of the holder K in such a manner that the cord passes into the notch G or G and then said stem is turned on its axis and at the same time pressed downward so that the two strands of the cord are wound on the stem and with the same are drawn down into the bore L of the holder. Then the cord is pulled downward whereby the stem is rotated axially with greatspeed in the holder and the top immediately rises to the ceiling, until the upper end of the rod H rests against the ceiling, on which end the top continues to turn or spin on the ceiling for a greater or less length of time, according to the force exerted lroo in pulling the. cord. Thecurved` spokes E serve tokeepwthe top` against the ceiling as long as it rotates at a certain speed.

To prevent the top from being thrown from 5 the ceiling by the impact, the rod H is pulled ,out of the upper end of the stern ashort distance before spinningthe top `and when the upper end of the said `rod strikesthe ceiling the rod is pushed into the bore of the stem and acts as a cushion to prevent the rebounding of the top and also prevents injury to th ceiling. I ain aware-thatspinningstops with propeller shaped blades which soar high into the 5 pigeons and I do not so broadly claim to be w the inventor of tops `that -rise when` being spun,` but, Y

i `Havingdescribed myi inventionywhat I 2c iclaiin asnew, and desire tosecure by Letters 1 Patent/ls- 1. The combination Witha Windwheel of a tubular stein projecting downward frein the air when spun, are old as Well as mechanicaltubular stein projecting from the same and a longitudinally split rod mounted to slide in the tubular stem, substantially as set forth. In testimony that I claim the foregoing as my invention I havesigned mynaxne, in presence of two Witnesses, this 23dday` ofi May, 1894.
